Give it a shove
“You don't feel like you're eating that much but the scale doesn't budge much. Here's how to give it a shove.”
You really need to keep track of what and how much you're eating. You don't need to do this forever, but you may need to do it for a couple of weeks at the minimum. The key is obviously writing down EVERYTHING you eat and then calculating the calories, fat, sodium, etc. This is a great education on nutrition and is a good tool to see where you're overdoing. Don't play the game of trying to calculate calories expended to justify an extra serving or piece of pie. Most people over-estimate calories burned and under-estimate calories eaten. Figure out a good ratio between healthy food, exercise, and treats and you'll see results on the scale.
